I began thinking about why am I constructing almost a shadow father or ghost father in my head into Graham Greene in response to the father who created me? What's going on here? I think a part of my sense is it's every boy's story. When we are kids, we imagine that to define ourselves or to find ourselves means charting your own individuality, making your own destiny and actually running away from your parents and your home and what you grew up with.

Suffering is a privilege. It moves us toward thinking of essential things and shakes us out of complacency. Calamity cracks you open, moves you to change your ways.

I think of the Dalai Lama as a doctor of the mind offering medicine and specific counsel and cures in the way a great doctor would.

I think people like me are in a relatively privileged position because we have to some extent chosen to live in foreign places. I would always make the distinction between those who are exiles in terms of being thrown out of the place they want to be, and others who are exiles in terms of going toward a place they would rather be.

So it is that Lonely Places attract as many lonely people as they produce, and the loneliness we see in them is partly in ourselves.

What is fascinating about a place like Los Angeles airport is that it is lots and lots of people, many of whom have saved up all their lives and channeled all of their energies toward coming to the promised land of abundance and plenty - the American Dream. But as soon as they arrive here they get a crash course in the American reality.

And if travel is like love, it is, in the end, mostly because it's a heightened state of awareness, in which we are mindful, receptive, undimmed by familiarity and ready to be transformed. That is why the best trips, like the best love affairs, never really end.
